Embodiment Construction

[0012] 1. Seed potato treatment

[0013] Under the condition of the temperature of about 20°C, soak the seed potatoes in a mixture of 58% metalaxyl 800 times solution and 1-2ppm gibberellin in a volume ratio of 1:1 for 2-5 minutes.

[0014] 2. Germination

[0015] Cut 3 / 4 of the treated seed potato near the top bud with a knife ring, divert the nutrients and auxin of the potato cubes to the side buds, prevent the top buds from growing excessively, thereby promoting the germination and growth of the side buds, and making the whole potato cubes sprout evenly. The ring-cut seed potatoes are placed on the soaked straw, stacked 3-4 layers according to one layer of straw and one layer of potatoes, and finally covered with a film to increase temperature and moisture, and stop germination when the buds grow to 2-3cm.

[0016] 3. Cut into pieces

[0017] The germinated seed potatoes are cut into pieces according to the specifications of 30-40g rhombic tetrahedron with a sterilized kn...

Abstract

The invention provides a pregermination method of potato in early winter, comprising the steps of processing potato, pregerminating, and slicing. The pregermination method is characterized by comprising the following steps: (a) potato seed processing: putting a potato seed into mixed liquor of 700-900 times of liquid of 58% of metalaxyl and gibberellin with concentration of 1-2 ppm at the volume ratio of 1:1, and dipping for 2-5 minutes; (2) pregermination: carrying out circumcision on processed potato seed by 3/4 near the terminal bud, putting on a wet straw, stacking 3-4 layers according to the principle that straw and potato are alternately arranged, covering by a film or a sack, and stopping pregermination when the length of the bud is 2-3 cm; and (3) slicing: slicing the pregerminated potato seed by a sterilized tool according to the specification of 30-40g of rhombic bisphenoid, wherein each rhombic bisphenoid has one bud; sterilizing the tool again after used for 10 minutes or when the tool cuts diseased and rotten potatoes; and naturally drying the sliced potato blocks until wound surface is suberized, and sowing. The invention can effectively lower potato consumption amount, prevent cross infection of germs (virus), lower rotten potato rate and improve rate of emergence.

Description

Technical field: [0001] The invention relates to a method for accelerating germination of winter early potatoes. Background technique: [0002] Pregermination of potatoes before sowing is a key link in winter potato planting. At present, there are two main types of germination of winter potatoes: whole potato germination and diced germination. Whole potato germination has less rotten potatoes in the process of germination, the emergence rate in the field is high, and the disease prevention effect is obvious, but the amount of seeds used is large. Cutting and accelerating germination can save seed potatoes, and it is beneficial to break the top advantage and germinate quickly. However, most of the existing cutting technology is to cut and accelerate germination before planting, which is prone to cross-infection of bacteria (viruses) and water loss of potato pieces, resulting in some potatoes. Blocks can not germinate or even rotten potatoes. Invention content: [0003] Th...
